Description
Compositions Containing Dialkyl Amino Acid Ester Salts FIELD OF THE INVENTION
[0001] The present technology relates to dialkyl amino acid ester salts that are useful for providing conditioning, softening, and/or cleaning properties in compositions. In particular, the present technology relates to dialkyl amino acid ester salts that are the neutralized (protonated) reaction product of an amino acid having at least two carboxylic acid groups and a fatty alcohol. The dialkyl amino acid ester salts can be used for hair care, as well as other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions.
BACKGROUND OF THE INVENTION
[0001] The present technology relates to dialkyl amino acid ester salts that are useful for providing conditioning, softening, and/or cleaning properties in compositions. In particular, the present technology relates to dialkyl amino acid ester salts that are the neutralized (protonated) reaction product of an amino acid having at least two carboxylic acid groups and a fatty alcohol. The dialkyl amino acid ester salts can be used for hair care, as well as other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions.
BACKGROUND OF THE INVENTION
[0002] There has been a trend in the personal care industry to formulate compositions with ingredients that are based on renewable resources derived from plants or animals, rather than fossil fuels. Such ingredients are considered "green" or "natural", since they are derived from renewable and/or sustainable sources. As a result, they are more environmentally friendly than ingredients derived from fossil fuels, particularly if they are also manufactured without the need for petroleum-derived solvents. An ingredient having a high Biorenewable Carbon Index (BCD, such as greater than 80, indicates that the ingredient contains carbons that are derived primarily from plant, animal or marine-based sources.
[0003] An example of a natural ingredient derived from renewable sources is a neutralized amino acid ester that is obtained from the reaction product of a neutral amino acid having a non-polar side chain reacted with a long chain fatty alcohol.
U.S. Patent No. 8,105,569 describes such neutralized amino acid esters. The neutralized amino acid esters are cationic, and therefore could potentially replace traditional cationic hair conditioning agents, such as behentrimonium chloride (BTAC) and cetrimonium chloride (CETAC), which traditionally have unfavorable environmental profiles.

The neutralized amino acid esters are cationic, and therefore could potentially replace traditional cationic hair conditioning agents, such as behentrimonium chloride (BTAC) and cetrimonium chloride (CETAC), which traditionally have unfavorable environmental profiles.
[0004] One drawback of the neutralized amino acid ester is that it is a more expensive cationic ingredient than other cationic components typically used in hair care compositions, such as quaternary ammonium compounds and amidoamines. In addition, a greater amount of the neutralized amino acid ester, compared to the traditional cationic active agents, is often required to achieve acceptable performance. Using more of an ingredient that is already more costly results in a more expensive product to manufacture.
It would therefore be desirable to have composition actives that are derived from renewable sources, but that can also deliver acceptable performance at lower cost, and at use levels comparable to the use levels used for traditional cationic active agents.
SUMMARY OF THE INVENTION
It would therefore be desirable to have composition actives that are derived from renewable sources, but that can also deliver acceptable performance at lower cost, and at use levels comparable to the use levels used for traditional cationic active agents.
SUMMARY OF THE INVENTION
[0005] The present technology is directed to dialkyl amino acid ester salts that are the reaction product of a neutralized (protonated) amino acid and a fatty alcohol.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The compositions of the present technology comprise one or more dialkyl amino acid ester salts that are derived from biorenewable sources, and provide conditioning, softening, or cleaning performance.
[0010] "Biorenewable Carbon Index" (BC!) refers to a calculation of the percent carbon derived from a biorenewable resource, and is calculated based on the number of biorenewable carbons divided by the total number of carbons in the entire molecule.
[0011] "Biorenewable" is defined herein as originating from animal, plant, or marine material.
[0012] The dialkyl amino acid ester salts of the present technology are obtained by esterification of (i) an amino acid having at least two carboxylic acid groups with (ii) a fatty alcohol, wherein the amine group of the amino acid has been protonated with an acid.
The dialkyl amino acid ester salts of the present technology may be represented by the structure of Formula (1):
R N
(1) N1-13 Formula (1) wherein R is a linear or branched carbon chain containing 1 to 10 carbon atoms, R1 and R2 are independently linear or branched alkyl groups containing 8 to 22 carbon atoms, preferably 8 to 16 carbon atoms, most preferably 8 to 14 carbon atoms, and A-is the anion of a proton-donating acid, preferably ethanesulfonate. The dialkyl amino acid ester salts of Formula 1 can have a selected distribution of the R1 and R2 alkyl groups. For example, in a given sample, at least 50 mol /0 of the R1 and R2 alkyl groups have from 8 to 16 carbon atoms, based on the total number of moles of R1 and R2 alkyl groups in the sample. Alternatively, at least 60 mol%, alternatively at least 70 mol%, alternatively at least 80 mol%, alternatively at least 90 mol%, alternatively at least 95 mol%
of the total number of moles of the R1 and R2 alkyl groups have from 8 to 16 carbon atoms.
In some embodiments, 100% of the total number of moles of the R1 and R2 alkyl groups in a given sample have from 8 to 16 carbon atoms (i.e., the R1 and R2 alkyl groups contain no C18-C22 alkyl groups). In other embodiments, 100% of the total number of moles of the R1 and R2 alkyl groups have from 8 to 14 carbon atoms. In some embodiments, 100%
of the total numbers of moles of the R1 and R2 alkyl groups have from 12 to 16 carbon atoms The dialkyl amino acid ester salts of Formula 1 can also have a selected distribution of the R1 and R2 alkyl groups wherein at least 80 mol /0 of the dialkyl amino acid ester salt molecules have from 24 to 30 carbon atoms in the combined R1 and R2 alkyl groups. The carbon chain distribution of the R1 and R2 alkyl groups is based upon the carbon chain distribution of the starting fatty alcohol reactant, which can be determined by gas chromatography.
The dialkyl amino acid ester salts of the present technology may be represented by the structure of Formula (1):
R N
(1) N1-13 Formula (1) wherein R is a linear or branched carbon chain containing 1 to 10 carbon atoms, R1 and R2 are independently linear or branched alkyl groups containing 8 to 22 carbon atoms, preferably 8 to 16 carbon atoms, most preferably 8 to 14 carbon atoms, and A-is the anion of a proton-donating acid, preferably ethanesulfonate. The dialkyl amino acid ester salts of Formula 1 can have a selected distribution of the R1 and R2 alkyl groups. For example, in a given sample, at least 50 mol /0 of the R1 and R2 alkyl groups have from 8 to 16 carbon atoms, based on the total number of moles of R1 and R2 alkyl groups in the sample. Alternatively, at least 60 mol%, alternatively at least 70 mol%, alternatively at least 80 mol%, alternatively at least 90 mol%, alternatively at least 95 mol%
of the total number of moles of the R1 and R2 alkyl groups have from 8 to 16 carbon atoms.
In some embodiments, 100% of the total number of moles of the R1 and R2 alkyl groups in a given sample have from 8 to 16 carbon atoms (i.e., the R1 and R2 alkyl groups contain no C18-C22 alkyl groups). In other embodiments, 100% of the total number of moles of the R1 and R2 alkyl groups have from 8 to 14 carbon atoms. In some embodiments, 100%
of the total numbers of moles of the R1 and R2 alkyl groups have from 12 to 16 carbon atoms The dialkyl amino acid ester salts of Formula 1 can also have a selected distribution of the R1 and R2 alkyl groups wherein at least 80 mol /0 of the dialkyl amino acid ester salt molecules have from 24 to 30 carbon atoms in the combined R1 and R2 alkyl groups. The carbon chain distribution of the R1 and R2 alkyl groups is based upon the carbon chain distribution of the starting fatty alcohol reactant, which can be determined by gas chromatography.
[0013] Preferably, the R1 and R2 alkyl groups are derived from a fatty acid source having an iodine value of less than 3. The iodine value represents the mean iodine value of the fatty acid source for the fatty alcohol feedstock. Most preferably, the R1 and R2 groups are fully hydrogenated. "Fully hydrogenated" means that any double bonds present have been almost completely removed by hydrogenation, but does not preclude the possibility that a small percentage of double bonds may remain. Although less preferred, the IR1 and R2 alkyl groups may be derived from a fatty acid source having an iodine value of greater than 3, i.e. the fatty acid source for the fatty alcohol feedstock has at least some double bonds, provided the esterification reaction between the fatty alcohol and the amino acid is performed under non-acidic conditions.
[0014] Esterification can optionally be facilitated by the use of catalysts including, but not limited to, titanium-based catalysts, such as those sold by E.I. DuPont de Nemours and Company under the name TYZOR , for example, titanium t-butoxide (TYZOR ) or ammonium salt of lactic acid chelate of titanium dihydroxide (TYZOR LA), and tin-based catalysts, such as dioctyltin bis-(2-ethylhexanoate) or dioctyltin dilaurate, available from REAXIS Inc., McDonald, PA.
[0015] Amino acids for the formation of the ester can be any that have at least two carboxylic acid groups. Particular amino acids include L-aspartic acid and L-glutamic acid.
[0016] To obtain the dialkyl amino acid ester salt, the amine group of the amino acid is preferably neutralized with an acid, and the neutralized amino acid is reacted with one or more fatty alcohols. Suitable fatty alcohols may be linear or branched, and may additionally be saturated and/or unsaturated, preferably saturated. The fatty alcohol can contain about 8 to about 22 carbon atoms, preferably 8 to 16 carbon atoms.
Specific examples of fatty alcohols that can be used include caprylic alcohol, capric alcohol, lauryl alcohol, myristyl alcohol, palmityl alcohol, stearyl alcohol, brassica alcohol, or mixtures or combinations thereof. Preferably, the fatty alcohols are derived from non-petrochemical sources. In some embodiments, the fatty alcohol is a mixture of fatty alcohols wherein between 65 wt% and 75 wt% of the alkyl groups in the fatty alcohol have 12 carbon atoms, between 20 wt% and 30 wt% of the alkyl groups have 14 carbon atoms, and between 3 wt% and 8 wt% of the alkyl groups have 16 carbon atoms, based on the total weight of alkyl groups in the fatty alcohol mixture. In some embodiments, the fatty alcohol can be derived from a coconut source, comprising a mixture of fatty acids having carbon chain lengths of 8 to 18 carbon atoms. The molar ratio of fatty alcohol reacted with amino acid is about 1.6:1 to about 4.5:1, alternatively about 1.7:1 to about 3.5:1, alternatively about 1.8:1 to about 3:1.

[0025] Compositions of the present technology, comprising the dialkyl amino acid ester salt, provide several benefits. The dialkyl amino acid ester salts have a BC! of at least 80, alternatively at least 90, and preferably of 100, meaning they can be derived entirely from natural sources. Having a BC! of 100 provides a benefit from an environmental standpoint, since such components are more environmentally friendly than components derived from petroleum sources. The hair conditioning formulations comprising the dialkyl amino acid ester salts provide better wet hair combing properties compared to formulations comprising Brassicyl L-Isoleucine esylate, a known neutralized amino acid ester, at comparable use levels. In addition, combining a glyceride component with the dialkyl amino acid ester salts of the present technology can further improve the wet combing properties of a hair care composition. Glycerides can be derived entirely from biorenewable sources, and therefore can have a BC! of 100. Thus, the combination of dialkyl amino acid ester salt and glyceride can also have a BC! of 100, and can deliver improved performance with an environmentally friendly profile. In addition, since the glyceride component is a less costly ingredient than the dialkyl amino acid ester salt component, the mixture of the dialkyl amino acid ester salt and glyceride component can provide better performance properties at a lower cost, compared to formulations comprising the dialkyl amino acid ester salt alone, and also compared to formulations comprising Brassicyl L-Isoleucine esylate. The hair conditioning formulations also provide better wet hair combing properties compared to formulations comprising CETAC.
However, unlike CETAC, the dialkyl amino acid ester salts of the present technology are biodegradable, and provide an improved environmental profile and lower toxicity compared to CETAC. The improved performance compared to CETAC is surprising, because typical cationic conditioning agents contain fatty carbon chains that are primarily C16/C18 carbon atoms or greater, whereas the dialkyl amino acid ester salts of the present technology have fatty carbon chains that are primarily C12/C14 carbon atoms.

[0026] Hair conditioning compositions comprising the alkyl amino acid ester salt component of the present technology can be applied to the hair in an amount suitable for obtaining a hair conditioning effect. Suitable amounts of the dialkyl amino acid ester salt as a conditioning active applied to the hair can range from about 0.001% to about 5% by weight, alternatively about 0.001% to about 2%, alternatively about 0.002% to about 1.5%, alternatively about 0.025% to about 0.5%, alternatively about 0.025% to about 0.25% by weight, as measured on dry hair. The hair conditioning compositions provide a wet combing Dia-Stron Maximum Peak Load of about 55 gram mass force (gmf) or less, alternatively about 50 gmf or less, alternatively about 45 gmf or less, such as about 20 to about 40 gmf. The hair conditioning formulas of the present invention have a pH of between 3 and 6, alternatively between 3.2 and 5.2, alternatively between 3.5 and 4.5.

The system was placed under a nitrogen headspace sweep, and the contents of the reactor were heated to 90 C.
Once at 90 C and the alcohol mixture appeared to be completely molten, the methanesulfonic acid was added dropwise over 50 minutes. The mixture turned dark brown (almost black), and as the system stirred, the aspartic acid congealed and collapsed into a ball making the mixture hard to stir. The temperature was increased in 10 C increments to a final temperature of 140 C. Once at 120 C, the "ball" of aspartic acid broke up and began to dissolve. Once at 140 C, the mixture became almost homogeneous with small amounts of a solid in the bottom of the flask.

[0043] The product is very dark and resinous. While not wishing to be bound by theory, it is believed that the double bonds in the oleyl alcohol are protonated during the reaction causing migration of the double bonds along with a number of unwanted side reactions. Therefore, it is desirable to minimize the amount of double bonds in the alcohol reactant. This product is designated SOAMS and is not within the scope of the invention.

Example 17: Comparative Conditioning Agents
[0050] Comparative hair conditioning compositions were prepared in accordance with the Table 1 formulation and following the General Procedure, except that different cationic surfactants or amine salts were used as the only conditioning active, instead of dialkyl amino acid ester salts of the present invention. The comparative conditioning actives were BTAC, CETAC and BLIE. Each of the hair conditioning compositions was evaluated for wet combing ability using the Dia-Stron MTT175 instrument and the wet combing procedure. Results are provided in Table 2.

[0051] As shown in Table 2, commonly used conditioning actives, namely BTAC and CETAC, yield Dia-Stron maximum peak load results of about 20 gmf and 70 gmf, respectively, when used at 2% active in a typical formula. BLIE, an amino acid-based conditioning salt, yielded a maximum peak load of about 156 gmf.

[0053] The hair conditioner containing LAES2:1 had a Dia-Stron maximum peak load of about 43 gmf, which is an improvement over the results obtained using CETAC. These results show that the dialkyl amino acid ester salt of the present technology can provide better wet combing properties than CETAC, a commonly used cationic conditioning agent (see CETAC results in Table 2). The results in Table 3 also show that a hair conditioning formula according to Table 1 containing 2% active LAES2:1 provides greatly improved wet combing properties compared to the composition comprising 2% BLIE, a known neutralized amino acid ester (see BLIE results in Table 2). The composition comprising BLIE as the conditioning agent, which has a BC! of 100, had a Dia-Stron maximum peak load of about 156 gmf, compared to the about 43 gmf maximum peak load achieved by the composition comprising the inventive dialkyl amino acid ester salt (LAES2:1) of the present technology, which also has a BC! of 100. These results demonstrate that conditioning performance does not need to be sacrificed when using a conditioning component that has a BC! of 100 (i.e. all of the carbons are derived from a biorenewable source).
[0054] The results in Table 3 further show that combining the dialkyl amino acid ester salt of the present technology with a glyceride component can improve the wet combing properties of the composition. The composition comprising the combination of LAES2:1 and glycerides had a Dia-Stron maximum peak load of about 36 gmf, compared to the about 43 gmf maximum peak load of the composition comprising LAES2:1 alone as the conditioning agent. It will also be appreciated that the glycerides are a less costly ingredient that the dialkyl amino acid ester salt. Thus, the mixture of glycerides with the dialkyl amino acid ester salt not only improves the wet combing properties of the cationic active, but also reduces the cost of the cationic active in the hair care composition.

(Compare Table 4 with Table 2).
Combining glycerides with LAES3:1 provides a slight improvement in the wet combing properties of the composition compared to LAES3:1 alone.

[0056] Dia-Stron wet combing results for hair conditioning formulas according to Table 1 and utilizing the Example 3 dialkyl amino acid ester salt (LAMS) as the conditioning agent by itself, and in combination with GMO are provided in Table 5. Since the LAMS
conditioning agent comprises 85% by weight LAMS active, the formula containing 2% by weight of the LAMS conditioning agent comprises 1.7% by weight of the LAMS
active, and the formula containing 2% by weight of the combination of LAMS and GMO
comprises a total conditioning active amount of 1.8% by weight.

85/100 GMO 1.8 33.0
[0057] The hair conditioner containing LAMS had a Dia-Stron maximum peak load of about 52 gmf, which is an improvement over the results obtained using CETAC.
These results show that LAMS can provide better wet combing properties than CETAC, a commonly used cationic conditioning agent. The results in Table 5 also show that a hair conditioning formula according to Table 1 containing 1.7 % by active weight dialkyl amino acid ester salt from Example 3 (LAMS) provides greatly improved wet combing properties compared to the composition comprising 2% BLIE, a known neutralized amino acid ester.
The composition comprising BLIE as the conditioning agent, which has a BC! of 100, had a Dia-Stron maximum peak load of about 156 gmf, compared to the about 52 gmf maximum peak load achieved by the composition comprising the dialkyl amino acid ester salt of the present technology, which also has a BC! of 100.
These results show that LAMS can provide better wet combing properties than CETAC, a commonly used cationic conditioning agent. The results in Table 5 also show that a hair conditioning formula according to Table 1 containing 1.7 % by active weight dialkyl amino acid ester salt from Example 3 (LAMS) provides greatly improved wet combing properties compared to the composition comprising 2% BLIE, a known neutralized amino acid ester.
The composition comprising BLIE as the conditioning agent, which has a BC! of 100, had a Dia-Stron maximum peak load of about 156 gmf, compared to the about 52 gmf maximum peak load achieved by the composition comprising the dialkyl amino acid ester salt of the present technology, which also has a BC! of 100.
[0058] The results in Table 5 further show that LAMS combined with a glyceride component can improve the wet combing properties of the composition. The composition comprising the combination LAMS and glycerides had a Dia-Stron maximum peak load of 33 gmf, compared to the about 52 gmf maximum peak load of the composition comprising LAMS alone as the conditioning agent. It will also be appreciated that the glycerides are a less costly ingredient that the dialkyl amino acid ester salt. Thus, the mixture of glycerides with the dialkyl amino acid ester salt not only improves the wet combing properties of the cationic active, but also reduces the cost of the cationic active in the hair care composition.

by weight of the Example 7 dialkyl amino acid ester salt (LGES3:1) (75.1%
active) as the conditioning agent. The hair conditioning composition was evaluated for wet combing properties.

Example 22: Conditioning Agent from Example 10 (Comparative)
[0059] SOAMS from Example 10 could not be successfully formulated into the Table 1 hair conditioner formula. Without wishing to be bound by theory, it is believed that the double bonds present from the leyl alcohol caused excessive side reactions under the acidic reaction conditions leading to the resinous, possibly polymerized product that would not formulate well. SOAMS is therefore outside the scope of this invention. It is therefore preferred that most of the carbon chains in the alcohol used to make the dialkyl amino acid salt be saturated.
